CARBURETER.

SPECIFICATION forming part of Letters Patent 1\I .d09,'831, dated August 30, 1898. Application led July 22, 1897. Serial No. 645,593. (No model.)

.To all whom it may concern,.-

Be it known that I, CLARENCE LE ROY PARKER, a citizen of the United States, residing at Silver Creek, in the county of Chautauqua and State of New York, temporarily residing at Washington, District of Columbia, have invented certain new and useful Improvements in Carbureters, of which the following is a specification. I

My invention pertains to apparatus for carbureting air or gas, and though susceptible of use in other relations or independently of other appliances is more especially designed for supplying gas for gas-engines.

In the accompanying drawings, Figure 1 is an elevation of my improved apparatus in connection with a gas-engine of common type; Fig. 2, asectional perspective View of the carbureter on a larger scale; and Fig. 3, a side elevation of a fender or guard which may be used in the carbureter or omitted, as preferred.

It is of course well understood that evaporation of oils and liquids takes place more rapidly at a higher than ata lower temperature and that such evaporation is greatly facilitated by converting the liquid into a fine spray or mist. It is likewise well known that rapid vaporization or evaporation of any liquid is attended by the absorption of heat from the surrounding atmosphere or medium 4 and that cold more or less intense may thus be produced. In its preferred or most advantageous embodiment my invention contemplates the utilization of both of these fac-4 tors, the water or other medium first used to cool the cylinder of a gas or vapor engine being utilized to assist in vaporizing any suitable oil or hydrocarbon and the rapid vaporization being availed of to coolthe water or circulating medium to lit it for continued use for cooling the engine-cylinder.

In many situations the requisite volume of water for maintaining the cylinder of a gas or vapor engine at proper working temperature cannot be had without considerable expense and inconvenience, and in some places its use is impracticable. This is true in places not supplied with a constant iiow of water or in small boats and launches, Where a proper supplyannot be carried aboard and there is not surplus power available for pumpa ,taining gasolene or other hydrocarbon.

ing it from outside the craft, and in various other situations. The extra cost where water is taken from a service-main is also an item of moment. i By my improved device I avoid all difficulty in this regard and render such engines available in all situations, besides `effecting rapid and perfect vaporization of the oil or hydrocarbon, carbureting the air or 'gas effectively, and doing this at a temperafture that tends to produce a permanent or fixed gas suitable for general use.

Referring again to the drawings, l indicates a gas or vapor engine of any common type, having its cylinder jacketed for circulation of a cooling medium.

` 2 indicates the carbureter, here represented as applieddirectly to a barrel or cask con- The construction of the carbureter is shown in Fig. 2, where it will be seen to consist of an external shell 3 in the form of two slightlytruncated cones united at their bases and 'containing a spiral coil 4 of pipe or tubing, vconforming in general outline to the shape of the shell or casing. Both ends of the shell are furnished with closing-heads, in which are formed inlet and exit openings.

5 indicates a pipe which communicates with the lower end of the chamber within the shell `or casing 2 and` is designed to enter the vesselin which is contained the hydrocarbon or `oil to be vaporized. That portion of the pipe `which is intended to be within the cask or ,vesselis perforated, as shown, and just above the perforations the pipe is encircled by a lclose-fitting screw-threaded plug or bushing 6, designed to screw tightly into the bung hole of the caskor vessel, as indicated. If

desired, the plug may be made in two parts, one screwing into the other and serving to vapply pressure to packing placed between them, thus producing a stuiiing-gland about ,the pipe 5 and preventing all escape of gas or vapor at that point.

Within the pipe `5 are two smaller pipes or `tubes 7 and 8, the former extending down through the pipe 5 tothe lower end thereof and having its upper end bent laterally, as shown. Pipe 8 passes through the side of pipe 5 and terminates just below and close to the laterally-bent end of pipe 7, so that when air, steam, or other fluid is forced through Ico pipe 8 a suction shall be produced in pipe 7, whereby the hydrocarbon or other liquid will be drawn up through said pipe 7 and thrown in the form of a spray into the chamber within the shell. In other Words, the pipes 7 and S are so formed, proportioned, and arranged as to produce the well-known spray or jet apparatus used in various connections at the present time.

Pipe 8 is furnished with a throttle-valve 9, by which to open and close it, and with a regulating-valve 10, which is designed to be set and left at proper working adjustment, so that the apparatus shall be ready for operation the moment the throttle is opened.

By thus avoiding the necessity of nicely adjusting the valve each time the apparatus is to be started I avoid a source of considerable delay.

gland where it passes to the outside of pipe 5.

To maintain the jet apparatus in condition forimmediate starting, a check-valve 12 is placed at or near the lower end of pipe 7, so

that oil raised therein may not flow back. ByY

this provision the pipe is kept always supplied with oil and no time is lost in raising it to the nozzle or discharge end of the pipe.

At the top of the shell or casing there is an outlet-pipe 13, which may pass to any desired place of storage or consumption, and beneath the outlet, but above the coil 4, there is arranged a guard or fender 14, composed of a series of disks of wire-gauze,perforated metal, or the like, slightly dishing in form. Successive disks are reversed in position-that is to say, one is placed convex side uppermost and the next concave side uppermost, as seen in Fig. 3.

In using the apparatus in connection with a gas or vapor engine the ends of coil 4 are connected with the water-jacket at two points differing in elevation as much as practicable. The outlet-pipe 13 is connected with the gasinlet of the engine, and the pipe 8 is connected with a blower or air-forcing device l5 of any suitable character. Other connections may of course be provided to carry off any surplus of gas or carbureted air produced by the apparatus.

Thus constructed and connected the action of the device is as follows: The blower or air-forcing device 15 is put in operation, and a stream or blast of air being blown through the delivery end of pipe 8 and across the end of pipe '7 the hydrocarbon is drawn up in pipe 7 and sprayed over the coil 4. The

,tapering form of the coil renders it a peculiarly good target for the spray, which encounters it from end to end, while any particles that coalesce and produce a drop fall back from the upper to the lower coils and nally run back through pipe 5 into the cask or vessel.l Any drops of oil thrown up through the center of the coil encounter the fender 14, by which they are intercepted. By reason of the inclination of the surfaces of the disks composing the fender the oil or hydrocarbon flows downward until it finally encounters the walls of the shell and runs down, or else it drops from the fender into the interior of the shell. Sufficient vapor to start the engine being thus produced and mingled with the air by which the spray is formed the charge is carried to the engine-cylinder and exploded therein. VAs the engine begins to operate and as one charge after another is exploded heat is developed in the cylinder, which is in great measure absorbed by the water in the surrounding jacket. In this way the water becomes heated, and by reason of the well-known law thehotter water rises to the top. As this occurs and as the hotter water flows along pipe 16, connecting with the upper end of coil 4, the colder water of the coil, cooled in` some degree by evaporation of the hydrocarbon in shell 3, flows in by pipe 17 to supply the place of the water passing over to coil 4. In this way a natural circulation of the water is established, which becomes stronger and more rapid as the heat of the water increases and the coil becomes more effective in hastenin g the vaporization of the oil or spray thrown against it. It will thus be seen that the action of the two agents, the heated water and the refrigerating-spray, is reciprocal, and if the parts be properly proportioned the water will be found to heat the sprayed hydrocarbon sufficiently to insure its complete vaporization and to produce a reasonably stable or fixed gas, while, on the other hand, the water is so far cooled by the time-it reaches the lower part of coil 4 that it is in iit condition to again absorb the heat of the engine-cylinder.

If desired, a reducing-valve may be applied to pipe 16 or 17 to control the rate of circulation of the water.

-It will be observed that the pipe 5 is of such size as to afford free communication between the interior of shell or casing 3 and the inside of cask or vessel 18, so that the pressure shall be equalized in the two and the free flow of oil through pipe 7 be accordingly insured.

I have shown pipe 13 as furnished with a branch containing a cock or valve whereby gas may be taken off to other points in any desired quantity within the capacity of the apparatus.

While I contemplate utilizing the heat of water employed to cool the cylinders of gasengines, I do not restrict myself thereto, but may use hot water, steam, or other heated fluid in the coil 4, the exhaust-steam of engines being available for the purpose, particularly where condensing-engines are employed. It is to be understood, therefore, that the invention is in no degree restricted IOO IIO

-sent the forni of a single cone each, though the double form is deemed best. It is also permissible to employ other forms of coil or manifolds, the essential feature being the exposure oi' large surface tothe spray.

Having thus described my invention, what I claim is- 1. A carbureter, consisting of an external shell; a heating-coil within the shell; an oilpipe; and an air-inlet pipe, the air-pipe being arranged to deliver its blast across the mouth ofthe oil-pipe and to deliver oil there- Y from, in the form of a spray, directly upon the Y heating-coil.

2. A carbureter, consisting of a shell or casing of conical or tapering form; a heatingcoil within said shell and of like form; an oilpipe; and an air-pipe arranged substantially as shown and described, whereby it is caused to deliver a blast of air across the dischargeopening of the oil-pipe and to project oil in the forni of a spray directly upon the coil, and whereby the air is thoroughly carbureted.

3. A carbureter comprising an upright shell in the form of two conical bodies united at their bases; a heating-coil of like form within the shell; a pipe for the introduction of earbureting liquid; and a pipe for the introduction of air, gas or steam under pressure, the latter pipe being arranged to deliver its blast across the open `end of the liquid-pipe, and

v both said pipes having their outlet-openings at the lower end of the shell; whereby the liquid is thrown in the form of a fine spray against the upper turns of the coil, and any particles which fall back are intercepted by the lower turns of the coil.

4. The herein -described carbureter, consisting of shell 3; oil-pipe' 7; air-pipe 8 arranged to deliver a blast of air across the opening of pipe 7 and a heating-00H4 located directly in the path of the spray produced by the blast of air across the oil-pipe opening; whereby the oil is delivered in the form of spray to the heating-coil and is vaporized by contact therewith.

5. The carbureter herein shown and described, comprising an outer shell 3; an internal heating-coil 4; an oil-pipe 7; a blastpipe 8; and a fender or guard let between the gas-outlet and the coil.

6. In combination with the Water-jacket of a gas or vapor engine; a carbureter consisting of a shell or casing, a heating-coil wholly contained within said shell and communicating with said water-jacket, and means for spraying oil or hydrocarbon upon the coil, whereby all the heat given off by the water is utilized within the carbureter to vaporize the oil or hydrocarbon, and the cooling effect of the spray is applied toevery portion ofl the coil to reduce the temperature of the water.

In witness whereof I hereunto set my hand in the presence of two witnesses.
